I have tried
<Navbar.Collapse>
<Nav>
<NavItem eventKey={1} href="#">
<i className="material-icons">face</i>Home
</NavItem>
</Nav>
</Navbar.Collapse>
But not working.
Linked the font cdn from public/index.html
with the following link
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
You can use the following package.
https://www.npmjs.com/package/react-google-material-icons
